Cleaned. Verified. Every time.
Commercial cleaning you can count on. A written scope, a photo-verified close-out report after every clean, and one owner personally accountable for the standard. The service is built for owner-operated professional offices across the Greater Toronto Area.
Keystone Facility Services provides recurring commercial cleaning for owner-operated professional offices, including accounting, law, mortgage, insurance, real estate, and healthcare practices of roughly 1,500 to 5,000 square feet across Toronto and the Greater Toronto Area. Core service areas include Toronto, Vaughan, Mississauga, Brampton, Markham, Richmond Hill, and surrounding business communities. Every client gets a written scope, a photo-verified close-out report after every clean, and one owner personally accountable for the standard.
Commercial only. No residential cleaning. How the model works
Reliability model
The service is intentionally narrow: recurring commercial cleaning for smaller professional offices where reliability, communication, and verification matter more than a low first quote.
Every visit closes with the Keystone Close-Out Report: verification photos and notes tied to your checklist. Completion is documented and sent to you, not assumed. It is how a small, owner-run company proves its standard instead of asking you to take it on trust.
An owner scopes your office, sets the standard, and reviews the close-out report after every clean. You are never handed to a call centre or a franchisee. The person responsible for the work is the person you deal with.
No call centre, no account manager between you and accountability. You deal directly with the person responsible for the standard, the schedule, and the follow-through.
Why offices switch
Ask any office manager who has fired a cleaning company and the story is one of these five. Keystone is structured against each one through the way the service is built.
The first weeks are strong, then details start slipping, and nobody can say exactly when the standard changed.
The Keystone answer: The written scope fixes the standard before service starts, and every visit closes against the same checklist. The standard cannot quietly drift, because every clean is measured against the same document.
When staffing changes without a reliable handoff, access details, restricted areas, and the office standard have to be learned again.
The Keystone answer: No honest cleaning company can promise the identical person on every visit, and Keystone does not make that promise. What stays fixed is the standard: your office runs on a written checklist, every visit is photo-verified against it, and the owner reviews each report. A change in who cleans never becomes a change in how your office is left.
You report a missed washroom and hear nothing back, or get a vague promise. Then it happens again.
The Keystone answer: There is no queue. The owner answers the phone, reviews the close-out report against the scope, and tells you what happens next.
An introductory price wins the contract, then quiet scope-trimming pays for it.
The Keystone answer: The quote is built from a walkthrough of your actual space, with the scope in writing. If something about the scope or price needs to change, it is discussed first; it is never absorbed silently.
Cleaning happens after hours. Without records, every dispute becomes your word against theirs.
The Keystone answer: Every visit ends with the Keystone Close-Out Report: photos and notes tied to your checklist. The proof exists before any question gets asked.

Proof without pretending
Keystone is a new company and says so. The trust model is operating discipline: Keystone is insured, WSIB-compliant, bonded, and owner-led, with The Keystone Close-Out Report after every clean. After every clean, the crew closes the visit with a report tied to your site checklist: verification photos of the areas that matter, completed-task confirmation, and written notes on anything that needs your attention. It arrives through the agreed contact channel by the written handoff time, so you never have to wonder whether the work was done.
Every clean is finished by the agreed time with a photo close-out report, or you hear from the owner first about why. If a clean is ever late or missed without that heads-up, that visit is free.

Common questions
The questions owners and office managers ask most before booking a walkthrough.
It depends on square footage, cleaning frequency, washroom count, floor types, and access requirements, which is why Keystone quotes only after a walkthrough. You receive a written quote within 24 hours of the walkthrough, with the full scope documented so you can compare it line by line against any other quote.
Every visit closes with the Keystone Close-Out Report: verification photos of the areas that matter, the site checklist marked complete, and notes on anything needing attention, such as locked rooms, supply shortages, or surface issues. You see proof of completion without being on site.
By not depending on any single person's memory. Your office runs on a written checklist, and every visit closes with a photo-verified Close-Out Report measured against it. The owner reviews each report, so the standard set in week one holds in week forty, regardless of who is on shift that night.
